“…The result is consistent with the hypothesis. The result may be due to that China across five climatic zones, namely, cold-temperate, temperate, warm-temperate, subtropical, and tropical (Xie et al 2001, Wu et al 2006, Weber et al 2008, Li et al 2009). Additionally, ecosystems in which the most alien invasive plant species occur have the same or similar climate with their natural habitat.…”

“…This observation is inconsistent with the hypothesis. This might indicate that southeastern China is heavily infested with alien invasive plant species, presumably because this part of the country has a mild climate (mainly subtropical and tropical) and is more disturbed by human activities than other regions in China (Wu et al 2006, Li et al 2009, Feng et al 2010. Thus, the AISPS in China contains abundant pantropic elements at the family level.…”

“…As the world's third largest country, China covers five climatic zones: cold-temperate, temperate, warm-temperate, subtropical, and tropical in which diverse ecosystems can receive a variety of alien invasive plant species from different biogeographic regions (Xie et al 2001, Wu et al 2006, Weber et al 2008, Li et al 2009. A wide range of habitats and environmental conditions enable China especially vulnerable to the successful establishment of the alien invasive floras originating from different regions because the potential alien invasive plant species from most areas of the world can find their suitable habitat somewhere in China ultimately (Xie et al 2001, Weber et al 2008, Yan et al 2014.…”

This study aims to determine the floristic characteristics of alien invasive seed plant species (AISPS) in China. There are a total of five hundred and thirteen AISPS, belonging to seventy families and two hundred and eighty-three genera. Seventy families were classified into nine areal types at the family level, and "Cosmopolitan" and "Pantropic" are the two main types. Two hundred and eighty-three genera were classified into twelve areal types at the genus level, and "Pantropic", "Trop. Asia & Amer. disjuncted", and "Cosmopolitan" are the three main types. These results reveal a certain degree of diversity among AISPS in China. The floristic characteristics at the family level exhibit strong pantropic characteristics. Two possible reasons for this are as follows. Firstly, southeastern China is heavily invaded by alien invasive plant species and this region has a mild climate. Secondly, southeastern China is more disturbed by human activities than other regions in China. The floristic characteristics at the genus level display strong pantropic but with abundant temperate characteristics. This may be due to that China across five climatic zones and the ecosystems in which the most alien invasive plant species occur have the same or similar climate with their natural habitat.

“…It is well known that biological invasion had direct impacts on and threats against native species survival and reproduction (Stinson et al, 2006;Kasenene, 2007;Mangla et al, 2008), regional biodiversity protection (Cui et al, 2011;Wang et al, 2010;Zhou et al, 2009a,b), ecological safety maintenance Li et al, 2013Li et al, , 2009, and environment health and development (Balasubramanian et al, 2013;Zhang et al, 2013;Zhou et al, 2009a,b), which has become a global ecological environment issue (Celesti-Grapow et al, 2010;Li et al, 2009;Pritekel et al, 2006). How to effectively control and scientifically manage the invasive species has become an important issue and a great challenge for biologists and environment protectionist.…”

a b s t r a c tLaboratory biological simulation experiment was conducted to investigate growth disturbance of high, moderate, low concentration of aqueous extracts (i.e. the original extracts with a solid-liquid ratio of 1:40 g mL −1 and its 5 times diluents and 25 times diluents) from several crops straw (residue) on Ageratina adenophora, a worldwide notorious invasive weed. The results showed: (a) aqueous extracts from several crops straw (residue) brought about different impacts on the single index for germination and growth of A. adenophora, e.g., high concentration of aqueous extracts from Brassica oleracea waste leaves showed a strong inhibition against the germination rate (GR) and germination index (GI) of A. adenophora, while high concentration of aqueous extracts from Vicia cracca straw showed a strong inhibition against radicle length (RL) and hypocotyl length (HL) of A. adenophora; (b) high concentration of aqueous extracts from B. oleracea waste leaves and high, moderate and low concentration of aqueous extracts from Oryza sativa straw and Triticum aestivum straw showed rather strong synthetic effects (inhibition) on GR and GI of A. adenophora, which could be chosen for the control over the seeds germination of A. adenophora; (c) high and moderate concentrations of aqueous extracts from V. cracca straw, high concentration of aqueous extracts from B. campestris waste leaves, and moderate and low concentrations of aqueous extracts from O. sativa straw and T. aestivum straw showed rather strong synthetic effects (inhibition) on RL and HL of A. adenophora, which could be selected as ideal materials for the control over the seedlings growth of A. adenophora; and (d) high concentrations of aqueous extracts from V. cracca straw, B. oleracea waste leaves and B. campestris waste leaves, and high, moderate and low concentrations of aqueous extracts from O. sativa straw and T. aestivum straw showed rather strong synthetic effects (inhibition) on GR, GI, RL and HL of A. adenophora, which could be selected as ideal materials for the control over the seeds germination and seedlings growth of A. adenophora. Thus, this study would provide a theoretic guidance and technical support for the resources utilization of crops straw (residue) and the prevention and control over invasive weeds as well.

“…Maintaining the integrity of the native ecosystems and conserving biodiversity in this estuary is of national importance. Therefore, two national reserves were established in 2005 in the estuary, one on Chongming Island and the other on Jiuduansha Islands (see Figure 1 in [21]). However, the mudflats and salt marshes in the two reserves are now heavily infested with introduced S. alterniflora, which may threaten the estuarine ecosystems and their biodiversity.…”

The relative contribution of long-distance dispersal and local diffusion in the spread of invasive species has been a subject of much debate. Invasion of the intertidal mudflats by Spartina alterniflora is an ideal example of stratified diffusion, involving both long-distance dispersal of seeds and local diffusion due to clonal growth. In conjunction with experimental data on range radius-versus-time curve, a traveling wave equation-based model is used to investigate the sensitivity of the spread rate of exotic S. alterniflora to parameters of long distance dispersal (c, maximum colonial establishment rate) and local colony diffusion (r, intrinsic growth rate) at two tidal marshes, the Eastern Chongming and the Jiuduansha Islands, at the Yangtze River estuary. Both Eastern Chong ming and Jiuduansha Islands are now national natural reserves in China, which were established in 2005. However, the mudflats and salt marshes in the two reserves are now heavily infested with introduced S. alterniflora, which may threaten the estuarine ecosystems and their biodiversity. S. alterniflora was first found in 1995 on Chongming. For rapid sediment accretion in mudflats in the estuary, S. alterniflora was also intentionally introduced to Jiuduansha in 1997 and Chongming in 2001, which has led to a rapid range expansion in the estuary. Our results show that range expansion of species with stratified diffusion is affected by both long-distance dispersal and local colony diffusion, and that there is a critical c * , below which the spread rate is more influenced by longdistance dispersal than by local diffusion. After applying this model to the invasion of S. alterniflora in the Yangtze River estuary, we derive that c = 1.7 × 10 −3 , c * = 0.126 and c = 4.8 × 10 −3 km −2 •yr −1 , * Corresponding author. W. Yang et al.3643 c * = 0.140 km −2 •yr −1 at Chongming and Jiuduansha (Shanghai), respectively. Our results suggest that the range spread of S. alterniflora in the Yangtze River estuary is more influenced by longdistance dispersal than local colony diffusion, and that S. alterniflora generates about 1.7 × 10 −3 to 4.8 × 10 −3 colonies per square kilometers per year. This study provides important information about dispersal dynamics of S. alterniflora that may be useful for finding optimal control strategies.
